James Franco, pictured here at the Venice Film Festival screening of "Spring Breakers," has been accused by a former NYU professor for making "disparaging and inaccurate public statements" after receiving a poor grade.

This probably isn't the sort of Barack Obama comparison that James Franco would want.

"Whoever was in Clint Eastwood's chair at the Republican National Convention was more present than Mr. Franco was in my classes," former New York University professor Jos Angel Santana told the New York Post in reference to his famous pupil, whom he's now suing for defamation.

Franco's rep couldn't immediately be reached for comment on this new development.

Calling the Oscar-nominated actor a "bully," Santana blasted Franco for making "disparaging and inaccurate public statements about him" after receiving the poor grade.

Per the Post, Franco had told reporters, "I didn't feel like I needed to waste my time with a bad teacher...No teacher will ever be fired from NYU for giving a student a D. He wasn't fired, he was asked not to come back after three years because they didn't think he was a good teacher."
